“I am one of the proprietors of the Lake Shore Nitro-Glycerin Works, situated near Painesville, Ohio. I am personally acquainted with Taliaferro P. Shaffner, and endorse all the evidence of G. M. Mowbray as to Shaffner’s proposal to consolidate the Nobel and Mowbray patents, and his admission that the parties he represented did not claim the exclusive right to manufacture Nitro-Glycerin. I would state that one W. B. Roberts, of the firm of Roberts & Co., of Titusville, Pennsylvania, informed me that he is one of the Trustees of the United States Blasting Oil Company, and that since the commencement of this suit I have delivered to Roberts & Co., at request of W. B. Roberts, twelve hundred pounds, or thereabouts, of Nitro-Glycerin manufactured by the company of which I am a member. “I manufacture (as a party interested in the Lake Shore Nitro-Glycerin Works of Painesville) under a license from George M. Mowbray, under a patent to said Mowbray, bearing date April 7th, 1868.” February 25, 1870. J. H. KING. Evidence of James Dickey. “I am acquainted with Nobel’s system of blasting. I assisted in making ten explosions in Oil City Tunnel, for Charles Lobb, the contractor. We did not use any of the methods of exploding specified in Nobel’s or Shaffner’s patents. We used the improved electrical machine of H. Julius Smith, patented August 10, 1869, and used the method of firing and fuse described in G. M. Mowbray’s patent of July 27, 1869, and which several methods are entirely different from those mentioned in the several patents claimed by complainant in this case. I used in the blasts made by me, the Nitro-Glycerin manufactured by the Lake Shore Nitro-Glycerin Company, under Geo. M. Mowbray’s patent, No. 76,499, dated April 7, 1868. I endorse the statements of the miners Mackey and Lynch as to the noxious effects and danger arising from the use of Shaffner’s Nitro-Glycerin, and the freedom from the same in that manufactured by Mowbray’s system.” February 25, 1870. JAMES DICKEY. Evidence of W. S. Holbrook. “I was engaged along with James Dickey to perform some blasting in Oil Creek Tunnel. I endorse his statement as to the kind of Nitro-Glycerin and the method of exploding used in said tunnel, and further state that we never used any other process or material.” February 25, 1870. W. S. HOLBROOK. Evidence of Henry H. Pratt.
